Class NatLayerPainter

java.lang.Object
  org.eclipse.nebula.widgets.nattable.painter.layer.NatLayerPainter

All Implemented Interfaces:

ILayerPainter

Direct Known Subclasses:

NatGridLayerPainter

public class NatLayerPainter
extends Object
implements ILayerPainter

ILayerPainter implementation that is rendering the background of the space that is available for the NatTable instance. It uses the Color that is configured via Control.setBackground(org.eclipse.swt.graphics.Color). It then calls the ILayerPainter of the underlying layers in the layer stack and calls all registered IOverlayPainter at the end, to render the overlays correctly.

paintLayer

public void paintLayer(ILayer natLayer,
                       org.eclipse.swt.graphics.GC gc,
                       int xOffset,

Specified by:

paintLayer in interface ILayerPainter

gc - GC used for painting

xOffset - of the layer from the origin of the table

yOffset - of the layer from the origin of the table

rectangle - area the layer can paint in

configRegistry - in use by NatTable. Useful for looking up associated painters.

paintBackground

protected void paintBackground(ILayer natLayer,
                               org.eclipse.swt.graphics.GC gc,

Description copied from interface: ILayerPainter

This method is used to adjust the cell bounds when painting the layer. This is most often used to reduce the size of the cell to accommodate grid lines.
